SEROLOGICAL BACTERIAL INFECTION

method of choice for detection of H. pylori

• ELISA

• CLOtest

• LFA

• ASO

positive test for CLOtest would indicate:

• positive: pink

  increase pH

• positive: yellow

  increase pH

• positive: reddish-pink

  decrease pH

• NOTC

not aggluntination but rather a low grade precipitation reaction

• flocculation

• hemagglutination

• latex agglutination

• NOTC

Potent toxic proteins released from living bacteria

• Exotoxins

• Endotoxin

• Capsule

• Antigen O

toxins that are found in both gram (+) and gram (-) bacteria

• endotoxins

• exotoxins

• capsules

• LPS

Damages glomeruli, producing hematuria, proteinuria, edema, and hypertension

• group A strep

• group B strep

• group D strep

• NOTC

Major cause of gastric and duodenal ulcers and can survive in acid environment of stomach

• H. pylori

• V. cholerae

• E. coli

• S. typhi

Streptococci are:

I. gram positive bacilli corkscrew shape

II. gram negative cocci in linear

III. gram positive cocci in cluster

IV. gram positive in sperical and ovoid shape

• I, II, III, and IV

• II and IV

• II only

• IV only

the major virulence factor of GAS and has a net-negative charge at the amino-terminal end

• M protein

• A protein

• LPS

• Exotoxins

detects all products of antibodies to assays for detection

• streptozyme

• anti-DNAse B

• anti-streptolysin O

• NOTC
